Yes, the easiest way is to reload the config file.
However, you can do this several ways:
1. Instead of using PropertyConfigurator::configure(), use
PropertyConfigurator::configureAndWatch(), which will start a new
thread that will periodically check the config file for changes.
2. Watch the file using some sort of system file notification
API(inotify on Linux; look at QFileSystemWatcher if you use Qt) and
then call PropertyConfigurator::configure().
3. Completely ignore the config file and change settings via code.
This is more complicated, but you can do things like change log levels
and add/remove appenders via the API, which is essentially what
PropertyConfigurator::configure() does in the first place.
